OP12 Mirikizumab improves fatigue, bowel urgency, and quality of life in patients with moderately to severely active Crohn’s Disease: Results from a phase 3 clinical trial
Bibliographic record
Abstract
Abstract Background Mirikizumab (miri), an anti-IL-23p19 antibody, is approved for the treatment of ulcerative colitis and under development for Crohn’s disease (CD). We investigated how miri impacted fatigue, bowel urgency, and health-related quality of life (HRQoL) through 52 weeks in patients with moderately to severely active CD in the Phase 3 VIVID-1 study. Methods In the treat-through VIVID-1 (NCT03926130) study, patients (N=1065) with moderately to severely active CD and a Simple Endoscopic Score for CD (SES-CD) score ≥7 (or ≥4 for patients with isolated ileal disease) and failure to biologic and/or conventional therapy were randomized in a 6:3:2 ratio to receive miri (N=579) (a single 900mg intravenous (IV) dose at W0, W4, and W8 followed by a subcutaneous (SC) dose of 300 mg at W12 and then every 4 weeks), ustekinumab (N=287) (6mg/kg IV at W0 and SC dose of 90mg at W8 and then every 8 weeks), or PBO (N=199). At W12 PBO responders continued PBO to W52; PBO-non-responders received the same blinded miri regimen as described above. This analysis focuses on results in patients randomized to either miri or PBO. The change from baseline for Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Urgency Numeric Rating Scale (UNRS), and Inflammatory Bowel Disease Questionnaire (IBDQ) total and domain scores (bowel symptoms, systemic symptoms, emotional function, social function) were analyzed through W52. IBDQ response (≥16-point improvement from baseline) and remission (total score ≥ 170) rates were also analyzed at W12 and W52. For binary variables, adjusted risk differences were compared between miri and PBO using the Cochran-Mantel-Haenszel (CMH) test. For continuous variables, least squares mean changes from baseline were compared between treatment groups using ANCOVA. Results Significant improvement in mean change from baseline to W12 and W52 were observed with miri for FACIT-F, UNRS, and IBDQ total and domain scores (all p<0.000001 at W52) (Figure 1&2). Miri-treated patients showed improved UNRS scores versus PBO as early as W8 with statistical significance sustained to W52 (Figure 1B). At W12 and W52, a greater percentage of miri-treated patients achieved IBDQ response (W12: p<0.000001; W52: p<0.000001) and remission (W12: p<0.000001; W52: p<0.000001) compared to PBO (Figure 2A&B). Conclusion Treatment with miri resulted in improvements in fatigue, bowel urgency, and HRQoL at W12 and W52 in patients with moderately to severely active CD.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
